Trigger

A trigger, or photosensor, detects products as they move along theproduction line, and provides input to the EPC-15 pattern control. Threetriggers can be equipped for complex patterns or dual-gluing applications.Nordson offers the following types of triggers:

� a retroreflective photosensor� a retroreflective photosensor with polarized lens� a diffuse-reflective photosensor� through-beam emitter/receiver photosensor

The type of trigger to be used depends on the reflectivity of the productbeing sensed and the lighting conditions within the sensing area.

System Overview2-4


321352D02Issued 2/10

Power Supply

The EPC-15 pattern control requires an external power supply to convertfrom AC to DC power. Nordson offers two different power supplies:

� a 2.5 A power supply in an IP54 sealed enclosure� a 2.5 A power supply in an unsealed enclosure

Both are autoranging units that can accept power from 90 to 135 VAC orfrom 175 to 264 VAC and convert it to a regulated 24 VDC.

The power supply must be sized to handle the total load of all guns plusthe load of the EPC-15 pattern control. For information on selecting apower supply for your system, refer to System Design in Installation.

Gun

The EPC-15 pattern control operates one or more adhesive-dispensingguns, up to four guns total. Use either pneumatic solenoid valves orelectric gun drivers, depending on the type of guns used.

The EPC-15 pattern control incorporates some advanced features andnew technology that include:

� Setup Capabilities� Operational Capabilities� Application Capabilities

Several time−saving features include:

� autoscaling� quick pattern definition� copy, paste, and delete functions

4. System Capabilities

Setup Capabilities

System Overview 2-5


321352D02Issued 2/10

Autoscaling

The EPC-15 pattern control’s autoscaling feature determines the linespeed based on a product’s length. The pattern can then be entered interms of distance instead of time. This saves setup time by avoiding amanual computation of line speed.

Quick Pattern Definition

Measure the length of each bead and the distance from the leading edgeof the product to the start of the bead. Then select the beads by gun andbead number, and enter the measurements in either time (default option),millimeters, or inches to define patterns.

The following figure shows a typical bead (bead 2 from gun 1) and themeasurements required to define it.

� bead offset 120 mm (4.7 in.)� bead length 30 mm (1.2 in.)

Enter these bead measurements into the system as indicated below:

The EPC-15 pattern control simplifies system operation by providingaccess to real-time data about system variables for on-the-spotadjustments to patterns or bead volume when needed. The differentoperational capabilities of the system are described below.

Online Pattern Adjustment

Online pattern adjustment fine-tunes patterns as they are generated onthe production line. For example, to increase the length of a particularbead by two millimeters, select the appropriate gun number and beadnumber and press the up key twice to add 2 mm. The program numberwill change to two dashes (−−) to show that the active program has beenchanged. Return to or overwrite the original program with the revisedsettings at any time.

The type of trigger to be installed determines the procedure to befollowed. A limit switch can be installed, or any of the following types ofphotosensors can be used as a trigger:

� a retroreflective sensor (with standard lens)� a retroreflective sensor (with polarized lens)� a diffuse reflective (proximity) sensor

1. Select a location for the trigger as directed by the objectives in thefollowing table.

Objective Recommendation orRequirement

Protect trigger from water and dust Choose a suitable place for theIP54 enclosure (which is splashand dust resistant).

Ensure good product sensing

NOTE: The sensor should beplaced 2 in. from product. Thisprevents outside sources fromtriggering the sensor (falsetriggering).

Make sure the distance betweenthe trigger lens and the target iswithin recommended range:

� Diffuse reflective (proximity)type: 51−381 mm (2−15 in.)

� Retroreflective type (polarizedlens): 51−2130 mm (2−84 in.)

� Retroreflective type(non-polarized lens):51−4500 mm (2−180 in.)

Avoid exceeding the controllerqueuing capability

Choose a location that will notpermit more than four productsbetween the trigger and guns atany time.

Ensure proper operation of patterncontrol

Make sure the time between thetrigger and the first bead of eachgun is greater than 2milliseconds plus the time forgun to fire adhesive.

NOTE: For random-lengthoperation, the trigger must befarther from the gun than thelongest pattern length (i.e.,the distance from trigger togun is greater than thedistance from the start of thebox to the end of the lastbead).

Maximize accuracy With pattern control operation inmind, install the trigger as closeto the guns as possible tominimize the effects of linespeed variance. Farthermounting distance of the triggerrequires more stable linespeeds.

Stitched Bead Patterns

Stitched bead patterns provide a way to reduce adhesive usage andincrease bond strength. Enter the percentage of glue savings desiredand a stitch interval. The controller automatically determines the stitchpattern that will provide the desired savings. It does this by dividing eachoriginal solid bead of a pattern into sub-beads with spaces betweenthem.

For example, if the adhesive savings for a bead pattern is set to 30percent, the stitched beads will be produced with 70 percent of theadhesive used to produce the original non-stitched beads. The patterncontrol always places a sub-bead at the beginning of the original solidbead and at every interval thereafter. Sub beads may not line up with theend of the original bead, but it will never go past it.

Control the amount of adhesive used by entering the gun savings andgun interval savings explained in the table on page 4-19. If the resultingpattern does not have sufficient bond strength, a quick adjustment to thepercentage savings can be made. Adjust the percentage to themaximum possible adhesive savings without loss of bond strength.

Trigger Minimum

Set the minimum allowable distance (generally the product length)between trigger events for trigger 1 and (if used) triggers 2 and 3. Thisfeature is used to ignore unwanted triggers from the product.

This feature is not needed unless the product has gaps in it, resulting inmultiple triggers per box.

Speed

Set the speed of the production line. If speed is known, enter it directly.Otherwise, use the autoscaling procedure.

Autoscaling

Automatically determine the line speed, given a known product length.

Provide to the EPC-15 pattern control the length of the pattern thatpasses under trigger 1, and the system will compute the required speed.Refer to the following figure for an example of using this procedure.

Use the following table to determine why the EPC-15 pattern controlgenerates pattern sets on some products but not on others. If it is notgenerating pattern sets on any products, refer to All Patterns Missing inthis section.


Possible Causes (Specific) Recommended Action

Incorrect trigger setup Trigger alignment or sensitivity isborderline, causing the trigger to sensesome products and not others

Refer to Adjusting a Trigger in Installationand check trigger alignment andsensitivity

Incorrect setting fortrigger minimum

Setting (for the minimum distancebetween trigger events) is too high

Check setting for trigger minimum. Itmust be less than product spacing (pitch)to prevent the controller from ignoringsome products. The control will ignore asecond trigger event that occurs beforethis minimum amount of line travel hasoccurred. Refer to UnderstandingProgram Options Settings in Setup

This part of the section contains procedures for isolating the cause ofcertain symptoms or for testing key parts of the EPC-15 pattern control.It includes the following procedures:

� Checking Gun Power Draw� Checking the Operation of a Single Gun� Checking Trigger Operation

NOTE: Make sure power to the unit is off.

1. Remove the terminal block cover from the unit.

2. Unplug the terminal block on the main control board that contains thewiring to the gun.

3. Measure the resistance across the terminals:

� Gun 1: measure across positions 3 and 4 of X1� Gun 2: measure across positions 5 and 6 of X1� Gun 3: measure across positions 1 and 2 of X2� Gun 4: measure across positions 3 and 4 of X2

4. Refer to the following table to interpret the results of the test.

Test Results Recommended Action

Resistance is 24 ohms or more

r � 24 ohms

None. The gun is drawing anormal amount of power.

Resistance is less than 24 ohms,but more than 4 ohms

4 < r < 24 ohms

The gun is drawing too muchpower. Reduce the load on thispattern control output.

Resistance is 0 ohms (or nearly 0 ohms)

r = 0 ohms

There is a short in the gun circuit.Find and fix the short.

5. Plug the terminal blocks back into the unit.

6. Re-install the terminal block cover on the unit.

7. Restore power to the unit, if desired.

3. Troubleshooting Checksand Tests

� the gun or gun actuator� the controller� some other part of the system

Then, refer to Single Pattern Missing (One Gun Not Firing) in this sectionfor specific troubleshooting advice.

1. Verify that the control is sending 24 VDC to the output for the gun asfollows:

a. Remove the terminal block cover.

b. Make sure the unit is stopped and enabled.

c. Enter the PURGE mode.

d. Select the gun to test.

e. Press ENTER to fire.

f. Ensure that the gun is dispensing adhesive.

g. Verify whether the green gun-output LED turns on.

Observation Conclusion Recommended Action

Gun dispersed adhesive and LEDturned on

The gun, gun actuator, and guncircuitry are working properly

Look for the cause of the problem inother parts of the system. Refer toSingle Pattern Missing (One GunNot Firing) in this section.

Gun failed to dispense adhesive,but LED turned on

Problem is in gun actuator(pneumatic solenoid valve orelectric gun driver), in gun circuitwiring, in melter, or in gun itself

Refer to troubleshooting for theseparts of the system in Single PatternMissing (One Gun Not Firing) in thissection.

Gun failed to dispense adhesiveand LED failed to turn on

24 VDC power is not being sent togun, gun is drawing too muchpower, or short has occurred in guncircuit

Unwire solenoid valve. Repurge thegun. If LED comes on, there is ashort. Check terminal connectionswith a DC voltmeter. Refer to TestVoltages in the TroubleshootingChecks and Tests section.

Use this procedure to check for proper trigger operation. The systemmay be equipped with one, two, or three triggers (photosensors).

1. Verify that the control is receiving an input signal from the trigger asfollows:

a. Remove the terminal block cover from the EPC-15 pattern control.

b. Locate the LEDs for trigger 1 (DS3), trigger two (DS4), and triggerthree (DS5) between terminal blocks X1 and X2.

c. Run a product past the suspect trigger.

d. Note whether the LED is turning on and off (or off and on).

e. If the LED is transitioning, the trigger is signalling. This indicatesthat the trigger is probably installed correctly and is not defective(refer to the following note). If the LED is not transitioning, continuewith step 2.

NOTE: Even if the trigger is signalling, the signal might beintermittent if the alignment or sensitivity setting is marginal. If theEPC-15 pattern control is not consistently generating a pattern set onevery product, refer to All Patterns Missing on Some Products in thissection.
